(also known as Claws of Steel or Claws of Iron) is a 1951 black-and-white Japanese horror film (J-Horror) directed by Nobuo Adachi for Daiei Films. It was shot in Black and White, Academy ratio full-screen, and was never dubbed in English. The film was never shown in the United States, and was only available on laserdisc in Japan.
A meek church worker who was once bitten by an ape on a jungle island in World War II begins to transform into a beast-man whenever he drinks alcohol. He develops a split personality like Jekyll & Hyde, one half adoring a virginal church organist, the other lusting after an immoral showgirl. A friend puts him into his nightclub act, showcasing his weird ability to transform from man to beast so effectively. At the climax, the man reverts entirely to bestial and wrecks a nightclub, taking a pretty showgirl hostage.
